The first step in the production of tungsten is to enrich tungsten from two minerals wolframite ((Fe, Mn)WO4) and scheelite (CaWO4) through the leaching process. The leaching residue usually contains a certain amount (2–5 wt%) of WO3 which is higher than that in the tungsten ore (generally less than 1 wt%). In addition, the leaching residue may also …
Glasses with nominal compositions shown in Table 1 were prepared by a melt-quenching method. Firstly, raw materials including reduced tungsten oxide (WO x, x<3), MF (M = one or two of Li, Na, and K), H 3 BO 3, SiO 2 and Sb 2 O 3 were uniformly mixed in the corundum crucible; then the mixture is heated at 1400 °C for 2 h to melt. Then, the melt was cooled to …

The U.S. Geological Survey (USGS) analyzes supply chains to identify and define major components of mineral and material flows from ore extraction, through intermediate forms, to a final product. Two major reasons necessitate these analyses: (1) to identify risks associated with the supply of critical and strategic minerals to the United States and (2) to provide greater …
As a strategic rare metal, tungsten is widely used in high-performance metallic materials like cemented carbide. The wet decomposition of scheelite CaWO 4 and wolframite (Fe,Mn)WO 4 is the primary and important step in tungsten metallurgy. According to the phase separation behaviors of the decomposition products, the wet decomposition processes of …
